Shouldn't this return nil ? : 1:4 user=> (find-first-result false? [true]) false
Maybe this definition of find-first-result may fill the gap: (defn find-first-result [pred coll] (find-first identity (map pred coll))) => 1:22 user=> (find-first-result false? [true]) nil 1:23 user=> (find-first-result #(when (= % 10) (* % %)) (range 20)) 100 1:24 user=> (find-first-result #(when (= % 10) (* % %)) (range 9)) nil HTH, -- Laurent 2009/4/27 Mark Volkmann <r.mark.volkm...@gmail.com>: > > find-first in seq_utils returns the first item in a collection where > (pred item) returns logical true.
